Is bonding exothermic
WebExothermic welding – also known as thermite welding or exothermic bonding – is a process for permanently joining earthing (grounding) or lightning protection conductors together. An exothermic weld can be especially useful for joining dissimilar metals. The process has the advantage in that it requires no external heat source and… WebBond Energy What makes a reaction endothermic or exothermic? Why? Chemical reactions can be a lot like playing with Legos ® —you must take apart part of your last creation before you can replace it with something new. For many chemical reactions, we have to first break bonds in the reactants before we can put the atoms back into a new …
